Permanent magnetic levitation apparatus

Abstract

A permanent magnetic levitation apparatus comprises a permanent magnetic track unit and permanent magnetic levitation wing unit provided on a magnetic levitation vehicle and levitated above the track unit, in which the wing unit includes a ferromagnetic wing trough having an open bottom, a wing permanent magnet disposed in the wing trough, and non-ferromagnetic spacers which are disposed between the side walls of the wing trough and the wing permanent magnet, and the track unit includes a ferromagnetic track trough having an open top, a track permanent magnet disposed in the track trough, and non-ferromagnetic spacers disposed between the side walls of the track trough and the track permanent magnet, so that the wing permanent magnet and the track permanent magnet are disposed so that their poles with the same polarities face each other. With the above apparatus, the static magnetic energy is concentrated on the open top of the track trough and the open bottom of the wing trough so as to generate great repulsion forces.

 a ferromagnetic track trough which is open at a top thereof and has a first side wall and a second wall opposed to each other, 
 a track permanent magnet disposed in the track trough, in which a N pole of the track permanent magnet is positioned at the open top of the track trough, 
 first and second non-ferromagnetic spacers which are disposed between the first and second side walls of the track trough and the track permanent magnet, respectively, 
 
 a permanent magnetic levitation wing unit on a magnetic levitation vehicle, the permanent magnetic levitation wing being levitated over the permanent magnetic track unit and including:
 a ferromagnetic wing trough which is open at a bottom thereof and has a first side wall and a second side wall opposed to each other, 
 a wing permanent magnet disposed in the wing trough and correspond to the track permanent magnet, in which a N pole of the wing permanent magnet is positioned at the open bottom of the wing trough so as to face the N pole of the track permanent magnet in the track trough, and the track permanent magnet has a width substantially equal to that of the wing permanent magnet, 
 
 third and fourth non-ferromagnetic spacers which are disposed between the first and second side walls of the wing trough and the wing permanent magnet respectively, wherein magnetic force lines of approximately parabola shape are generated from the wing permanent magnet to the first and second side walls of the wing trough, and from the track permanent magnet to the first and second side walls of the track trough, respectively. 
 
   
   
     2. The permanent magnetic levitation apparatus according to  claim 1 , wherein a thickness of the wing permanent magnet is approximately 1 to 3 times larger than that of the track permanent magnet. 
   
   
     3. The permanent magnetic levitation apparatus according to the  claim 2 , wherein the thickness of the wing permanent magnet is approximately 2 times larger than that of the track permanent magnet. 
   
   
     4. The permanent magnetic levitation apparatus according to the  claim 1 , wherein the wing permanent magnet is provided with countersinks for fixing the wing permanent magnet to a top of the wing trough by means of screws, and wherein the top of the wing trough is provided with countersinks for mounting the wing trough to a wing base for the vehicle. 
   
   
     5. The permanent magnetic levitation apparatus according to  claim 4 , wherein a thickness of the wing permanent magnet is approximately 1 to 3 times larger than that of the track permanent magnet. 
   
   
     6. The permanent magnetic levitation apparatus according to the  claim 5 , wherein the thickness of the wing permanent magnet is approximately 2 times larger than that of the track permanent magnet. 
   
   
     7. The permanent magnetic levitation apparatus according to the  claim 1 , wherein the track permanent magnet is provided with countersinks for fixing the track permanent magnet to a bottom of the track trough by means of screws, and wherein the bottom of the track trough is provided with countersinks for mounting the track trough to a track base.
